Abstract
In this paper, we discuss structural decoupling conditions for generalized multivariable systems. Some designing proceduree for decouple control have been investigated by many authors, but most decoupable condition depend on system parameters. It was shown that the structural decoupling condition could be derived with the aid of graph-representation by Linnemann for state variable systems.
The descriptor variable representation has an advantage that it can reflect physical structure of real systems. Therefore, a new decoupling condition for descriptor systems is derived via modified bipartite graphs. Further, it is shown that propsed results include the Linnemann's result.
